绘制一个整洁的饼图

Question

我画了一张饼图，但它太乱了！我附上了我的脚本生成的示例图像！

希望有人可以帮我绘制一张整齐的图表！

我的剧本：

graph

emotions = [neutral_avg,sadness_avg,disgust_avg,anger_avg,surprise_avg,fear_avg,happiness_avg]
labels = ['Neutral','Sadness','Disgust','Anger','Surprise','Fear','Happiness']
plt.pie(emotions,labels = labels,shadow=True, startangle=140,autopct='%1.1f%%')
date_string = time.strftime("%Y-%m-%d")
plt.savefig(date_string+'.png')

Answer 1

plt.pie(emotions, labels=labels, labeldistance = 1.3,pctdistance = 1.1,shadow=True, startangle=140, autopct='%1.1f%%')
plt.axis('equal')

修改labeldistance，pctdistance到你想要的。

Answer 2

你能试试：ax1.axis('equal')例子：

`fig1, ax1 = plt.subplots()
 ax1.pie(sizes, explode=explode, labels=labels, autopct='%1.1f%%',
    shadow=True, startangle=90)
ax1.axis('equal')`
